Eta_square or R_square in general mixed models

Postby Torvon » Thu Dec 22, 2011 4:32 pm

I am running Mixed Models (Analyse, Mixed Models, Linear) at the moment, with plenty of predictors in a big sample with longitudinal data.

I need to know which of my many significant predictors is the strongest, but can't find a way to have SPSS display some form of eta_square or r_square.

Could you tell me how to do this?
Thank you

I know that bumping is pretty uncool, but I'll give it another try.

I want to order 5 significant covariates in a mixed model by their "strength", however SPSS doesn't output any form of eta-square or r-square, and I don't see any option to do that either in SPSS.

Does anyone have a clue how I could do this?
It is important because we use the same 5 predictors for two outcome variables, and even if they are significant predictors for both we'd like to know in which model the influence is stronger.

Thanks
